My invention relates to a-heating device, and has particular reference to a stove using a gaseous fuel, of the type disclosed and claimed in my co-pending application forV patentl filed Sept. 29, 1925, Serial Number 59,284, in which I have described a structure having a communication with the atmosphere for leading into a closed area the outside air, and another communication with the Vatmosphere separated from said first named communication for continuously carrying out the air from the closed area, with a means for heating the incoming outside air. The present invention, involving the same aims and purposes as explained in my said above referred to application, is an improvement over the heater therein disclosed and it has for its chief object to provide a heater in which apart thereof constitutes an integral part of a structure or building in which the heater is to be placed, and in which such integral part of the heater constitutes a foundation or base for a flue or stack.

My invention is shown in preferred form the accompanying drawing, in which Fig. 1 is a front view partly broken.

Fig. 2 is a section on line 2-2-Fig. 1, and

p Fig. 3 is a perspective detail of the confduit.

In a: general sense my invention comprises a heating unit in combination with a case, of concrete, clay or other suitable fireproof material, which is arranged to be set in and form an integral part of a composite wall structure. g l

The case of concrete or other suitable material, forms an essential andintegral part of the heater, to eifect the objects mentioned, namely, to introduce the outside air into aroom or other closed area, to heat the introduced air and continuously to draw out the used air, thus providing for continual circulation and ventilation, which is modified only by the temperature of the heat employed.

By combining ,with the metallic heater structure a 'concrete or other fire resisting case which is nonconductive of heat, I obtain a complete insulation from the wooden 4. CLEVELAND G. TERRY, or TUJUNGA, CALIFORNIA.

parts of a building in which the heater is incorporated, eliminate fire hazards, conserve the heat, and provide a substantial support for the stack. In addition, the metallic struct-ure of the heater may be readily detached from and attached to the case.

In the drawing, the heater is shown as comprising a case 1 of concrete, ciay or other ireproof material, open at the front and bottom and having side walls 2, a top 3 and a back 1. An opening 5 is provided through the top 3 of the case 1, which in the upper face thereof is formed with a seatl 6 embracing the opening 5 and arranged to receive and support a flue or stack 7. The top 8 of the case l, as seen in Fig. 2, is preferably thickened in order to sustain the weight of the iue or stack 7, and at the respective sides thereof, tapers inwardly from the front, providing' thereby inclined faces 8 on each side of the case which are integral with the side walls 2 and which serve to deflect the heated airv into a room or other closed space.

As illustrated in Fig. 2, the case is of a depth generally equal to the thickness of the Vwalls in which it is to be placed, the front edge of the top conforming and arranged preferably to be on a line parallel with the finished wall. The heater structure which co-operates with the case 1, is a unit which, as seen in Fig. 1, is narrower than the case 1, and comprises a conduit 9, which is shown formed by a plate 9 having side walls 10, which maybe formed by bending the sides of the plate at substantially'right angles thereto. These side walls 10 are preferably flanged, as seen at 11 and the iianges are provided with holes, through which bolts 12 projecting from and embedded in the back 4L. of the case l are arranged to extend, nuts 18A being employed to associate the conduit 9 in permanent relation with the case l. The plate 9, as described, co-operates with the back t of the case 1 to form a closed passageway or the conduit 9 which communicatesat the top directly with the stack 7 and at the bottom is in open communication with a closed area or room to be heated and ventilated or both, the plate 9 for this latter purpose terminating a short distance above the bottom and providing a free en.-

. trance of the used heated air into the passageway, but the side walls 10 extending tothe bottom. To the lower portions of the side walls 10 are secured wings 14 which extend transversely and for the 'full ldepth of the device. These wings are conjoined on the top and at the forward ends thereof by a plate 15, which, withthe wings 14 and floor 16 constitutes substantially a passageway which is continuous with the passageway in the conduit 9, and servesto direct the used air in a closed area or room into the passageway in the conduit 9. In addition, these side wings-14 co-operate with the side walls 2 of the concrete case 1 to form lateral chiots 17 which are arranged to communicate with the atmosphere through pasv sageways 18,which maybe provided in the floor of a dwelling, room or other enclosure, as shown, to carry into thek closedareathe outside air, and they (the wings 14) also prevent the outside air from passing into the conduit 9, without tirst'having been heated and circulatedin the closed area. As seen, between the conduit 9 Vand the side walls 2 of the case 1, is provided a space B, which is in directcommunication with the ducts 17. The incoming outside air passes through the passageways 18, and through the lateral ducts 17 into thespaces B, from which it is drawn and heated by any suitable means, such as'shown, and comprising a plurality of flues 19 at their upper ends in free'comiminication with the conduit- 9 nearthe top of same, and at their lower ends connected'in-any suitable manner with a combustion chamber 2O,V disposed above the Vplate 15 and containing a. gas burner 21,supplied with a. vgaseous fuel from any desirable source.` The'lues 19 asshown, are spaced from the conduit 9 and from eachother thereby permitting the incoming atmospheric air-to circulate freely about said flues and be heated thereby before passing into the closed area. A cover 21 is provided to cooperate at the' ironty ofand with the con-- crete case 1,'in causing incoming outside air to pass within the heat zone, and'into contact with the lines. This cover 21 is provided with side panels 22, which close the front of the .spaces B between the conduit 9` and the side walls 2 of the case 1 thereby to cause the incoming air to be divertedbetween the tlues. This cover 21 is also formed with a lower,- horizontal panelr23, which prevents outside air passing through thepassageways V18 into the ducts 17ffrom entering directly into a closed area to be heated,without first having been heated by contact with the tiues 19. The panel 23 is .open at the bottoni, as

seen, at 24, to provide for Jfree and unimpeded passage of the used air from a closed area into the'conduit 9 vand from where it eventually passes in the stack 7. A suitable an integral part .or other closed space, after being heatedby contact with the combustion chamber 2O and the :lues 19. The" conduit 9 beingbpenat the bottom and in free communication with the closed area, and alsocommunicating` directly with 'the stack 7, the used air is educted from the room throughV this conduit 9,Y and the displacement ofr air in such room isk aided' by the kflue tenergy' into which the products-olf combustion? enter. rIn this-manner no staleair Vremains in a closed area, 'no `draits are created `and ventilation may beihad'whether 4the incoming air is heated or not. 7
